Detailed Description of the Invention

[0001]

TECHNICAL FIELD The invention of this application relates to a screen device. More specifically, the invention of this application is a new type in which it is easy to prevent the screen member from bending and to keep a pair of fixed or movable rod-shaped rigid bodies parallel to each other as a frame body to which the screen member is attached. The present invention relates to a screen device.

[0002]

2. Description of the Related Art Conventionally, in homes and office buildings, screen devices having various configurations have been used as opening and closing devices for windows and partitions.
Curtains, blinds, movable partitions, partitions, etc. are known as typical ones. And these are installed as various materials and various structures according to the purpose of use and use.

As one type of such a screen device,
Give the screen member itself as much independence as possible,
In addition, as a device that is easy to adjust the degree of opening / closing by a screen, for example, a device as shown in FIG. 2 is known. This is a screen member (1) which is processed into a pleated shape and can be folded and unfolded freely and has relatively good self-supporting property, and a movable frame part (2) to which the screen member is attached is slid to open the screen member. It is designed to open and close.

In such an apparatus, the pleated screen member (1) and the movable frame portion (2) are characteristic in design and operability, but the screen member (1) is sufficiently self-supporting. Instead, the left and right fixed frame portions (3) and (4) and the upper and lower fixed frame portions (5) serve as means for keeping the movable frame portion (2) in a predetermined position and guiding the movement thereof.
Although equipped with (6), it is difficult to keep the movable frame part (2) parallel to the left and right fixed frame parts (3) and (4) during its operation, and it is inevitable that the movable frame part (2) tilts to form a pleated screen. There is a problem that it is difficult to keep the member (1) self-supporting.

As a means for solving such a problem, as shown in FIG. 3, a rigid rod (7) or a wire member is stretched to keep the movable frame (2) in parallel, Means for increasing the independence of the member (2) are also known. However, in the example as shown in FIG. 3, since the wire member of the rigid bar member (7) is also exposed in the opening (8), it is very noticeable and the screen device is used for partitioning the room or the like. If this is attempted, the entrance and exit of the opening and the movement will be hindered, and the installation of furniture will be restricted.

Therefore, the inventors of the present application, in the device as shown in FIG. 3, do not expose the rigid rod member (7) and the wire member in the opening (8), and enter and exit the opening (8). As a device that can be moved without any hindrance, we have already proposed a Plitz screen opening / closing device that applies tension using a flexible member such as a thread or a wire. The screen device based on this completely new system has been put to practical use as a screen door, a partition, and the like, and has attracted attention in terms of design, structure, and operation.

However, in the screen device according to this new system, the members corresponding to the movable frame portion (2) in FIGS. 2 and 3 are kept and maintained in parallel with the left and right fixed frame portions (3) and (4), In order to slide, since the thread or wire is flexible and easily buckled, it is essential to use another structural member, and there is a constraint that the structure is inevitably complicated.

Therefore, with a simpler structure, the pleated screen member can be supported to freely contract and expand, its self-supporting property can be enhanced, and it is easy to keep parallel to the fixed frame portion. New means were desired.

BEST MODE FOR CARRYING OUT THE INVENTION The invention of the present application provides a novel screen device which has never been seen by the above-mentioned constitution, and the features of the constitution and the working effect will be described in more detail in the following embodiments. I will explain along.
Of course, the present invention is not limited to the following examples.

[0012]

1 of the accompanying drawings is a cross-sectional view illustrating the basic construction of a screen device according to the present invention. For example, as illustrated in FIG. 1, in the screen device of the present invention, a pair of rod-shaped rigid bodies (12) facing each other on the left and right sides.
(13), and has the opposite rod-shaped rigid body (12) (13)
As a screen mounting rod portion, a screen member (11) is mounted and supported between the respective members so as to be contractible and expandable. Then, between the opposed rod-shaped rigid bodies (12) and (13), two rod-shaped bodies (14) and (1) are arranged in parallel above and below the rigid body.
Each of 5) is fixed to the rod-shaped rigid body (13) at one end thereof, and the other end of the rod-shaped rigid body (12) is provided at the other rod-shaped rigid body (12) by the bending contact guide component (16) provided in its internal space. ) Is curved and guided in the axial direction. Then, the ends (14) of each of the rod-shaped bodies (14) (15) are
A) (15A) is connected with a highly buckling thread (17) or wire, and the thread (17) or wire is x
The intersections form a closed loop, and in such a configuration, the rod-shaped bodies (14) and (15) are connected to each other.

In this structure, the first rod-shaped rigid body (1
Regarding the second rod-shaped rigid body (13) in 2),
It may be a rigid body made of metal, wood, resin or the like, and may have a shape such as a hollow body. Then, is one of these, for example, the first rod-shaped rigid body (12) fixed to, for example, a wall surface, a window opening end portion, a pillar, or the like, and is the other second rod-shaped rigid body (13) movable? , Or vice versa. Further, both of them are movable, and one of them is temporarily fixed, and the other is moved so that the screen member (11) can be folded, contracted, or pulled out.

With respect to the screen member (11), the rod-shaped members (14) and (15) pass through the flat surface portion forming each pleat portion of the screen member (11) or the peaks (valleys) of the pleat portion. In, the sliding contact is made via a ring fitting or the like. As a result, the self-supporting property of the pleated screen member (2) is better maintained. Further, in the case where the screen member (11) itself has good self-sustainability, or in the case of a screen device of a relatively small scale, the rod-shaped bodies (14) (15) have upper and lower end portions of the screen member (11). It may be arranged outside the.

Each of the pair of rod-shaped bodies (14) and (15) is made of a material that is unlikely to buckle when a compressive force is applied in the axial direction and has a low Young's modulus in the axial direction. For example, with the above configuration, the rod-shaped rigid body (12) (13)
Can be moved to the left or right while maintaining the parallel.
The screen member (11) attached and supported to these can also be made to be self-supporting and can be folded and unfolded.

As described above, the rod-shaped bodies (14) and (15) are made of a material that is less likely to buckle when a compressive force is applied in the axial direction and has a low Young's modulus in the axial direction.
Between the rod-shaped rigid bodies (12) and (13), the rod-shaped bodies (14) and (15) above and below the rod-shaped rigid bodies (12) and (13) are curved guide parts (16).
The rod-shaped rigid bodies (12) and (13) are always kept in parallel with each other by keeping them tense and kept equidistant between them while being locked by.

A rod-shaped body (1
4) Examples of (15) are low-burning steel ropes and the like. The bending guide component (16) may be, for example, a plurality of rotating pulleys, or may be fixed as a curved body. The highly buckling thread (17) or wire forming the closed loop is always a bar (14).
Tension is applied to (15). Since they intersect x,
Each of the rod-shaped bodies (14) and (15) moves left and right at the same distance. As a result, rod-shaped rigid bodies (12) (13)
Remain parallel to each other.

An intermediate wire (19) may be provided at an upper and lower intermediate position between the rod-shaped bodies (14) and (15), and like the rod-shaped bodies (14) and (15), the intermediate wire ( 19), one end of which is fixed at the fixing portion (131) of the one rod-shaped rigid body (13) and the other end of which crosses x with the rod-shaped bodies (14) and (15) with high buckling property. The end is connected to (17) or a wire.

The intermediate wire (19) may be a more flexible wire member, thread or the like. However, in either case,
The intermediate wire (19) is stretched so that a required tension is applied between the fixing point to the rod-shaped rigid body (13) and the connection point to the highly buckling thread (17) or the wire. There is. Then, penetrating the screen member (11),
Or, it is designed to be in sliding contact with this.

It is to be noted that the terms "left and right" and "upper and lower" in the definitions and explanations of the present invention are in accordance with the explanations of the drawings starting from FIG. Naturally, the present invention also includes a device in which the screen member (11) is opened and closed in the up and down direction by replacing the "left and right" and "up and down" into "up and down" and "left and right".
Of course, the present invention is not limited to the above examples, and various aspects are possible in its details.
